Is there a max fall damage?
Is there a max fall damage? The basic rule for fall damage in D&D 5e is that a character takes 1d6 points of damage for every 10 feet fallen, up to a maximum of 20d6.
Do heavier objects fall faster?
Heavier things have a greater gravitational force AND heavier things have a lower acceleration. It turns out that these two effects exactly cancel to make falling objects have the same acceleration regardless of mass.
